Grails - converting a String to Date and then back to String

I've got this string 21-04-2016 for instance, that I'm trying to convert to a date. After that's done I need to flip it around, remove all the dashes and then convert it back to a string so that it looks like 20160421. I have found some code that I'll post below but I want to know if there is a simple way of doing this, maybe without having to convert the string to a date? Anyhow, here's my (broken) code:

String from = region.startDate    //I get this string from a controller
Date fromDate = Date.parse('yyyy-MM-dd', from) //.parse is depricated apparently
println(from)
println(fromDate)

Here's what I get back (from the println):

No need to convert from String to Date in that case (you could use a SimpleDateFormat (or rather two) to do that, though); just use String and List operations from Java and Groovy:

from.split('-').reverse().join()
